Because pink glitter will never not be the choice of any little one with a taste for fun footwear, our cute glitter trainers are the kid’s wardrobe essential. With two riptape bands to give secure wear for all day comfort, a rubber toe cap and white contrast sole give these kids’ trainers a classic sporty look. With stitch and trim details as well as a cute stripe on the sole, little feet are sure to love these sparkly trainers.
